generation is enabled (SOFE bit is one).
This bit is cleared when the USB Resume has been sent or when a USB reset is requested.
Writing a zero to this bit might be useful when a device disconnection is detected (UHINT.DDISCI is one) while a USB Reset is
being sent.
Writing a one to this bit will generate a USB Reset on the USB bus.
